Dynamax Gyarados: Is It Worth 400 Magikarp Candy After Max Monday?

Dynamax Magikarp makes its debut in Power Spots today, and the search traffic tells you exactly what everyone is really asking. Nobody wants a 310 CP fish. They want to know whether the thing at the end of the 400 candy tunnel is worth walking through.

Short answer: Dynamax Gyarados is a fine body with a bad tier placement, and today is still worth playing. Here is the actual math before you dump your candy jar into it.

If you are hunting a spare Magikarp or a finished Gyarados instead of grinding one, the live trade feed is the faster route. Read the Max Move warning further down first though, because trading a Dynamax Pokemon costs you something most people do not expect.

Max Monday details

That Rare Candy XL bonus is the quiet winner here. It is per in person Max Battle, and Rare Candy XL is the single most annoying resource in the game to farm otherwise.

The fight itself

Pure Water, so it is only weak to Electric and Grass. It resists Fire, Ice, Steel, and Water at 62.5 percent, which mostly matters because it means half your Max Battle bench does nothing here.

A 29 attack stat on a Tier 2 boss means this fight is a formality. Community counter data has it going down solo for anyone with a half decent Dynamax bench, so do not burn a group invite on it unless you are helping somebody new.

Counters worth bringing

Rillaboom is the clear standout because Grass hits hardest here and it has the bulk to sit in the fight. If you do not have it, any Grass or Electric Max attacker clears this at a comfortable pace.

Shiny odds, and what people get wrong

Niantic does not publish shiny rates, so treat every number you see as a community estimate. Trainer data on non legendary Max Battle bosses has generally landed around 1 in 128, with legendary Dynamax encounters sitting far better at roughly 1 in 20. Nothing official has confirmed a boosted rate for Magikarp specifically today.

That matters for planning. At 400 Max Particles a battle and a 1000 particle storage cap, you are not doing 128 of these. You are doing a handful. Go in expecting Rare Candy XL and candy, and treat a gold Magikarp as a bonus rather than the plan.

The 400 candy question

Evolving costs 400 Magikarp candy, same as it always has. Here is what you get for it.

Three Max Move types on one body is genuinely rare, and its bulk is well above average for something with that attack stat. So why the shrug?

Because the tier lists are brutal about it. Pokemon GO Hub places Dynamax Gyarados in D tier on the Max Attackers list. The Water order above it runs Gigantamax Inteleon and Gigantamax Kingler in S, Gigantamax Blastoise in A, Dynamax Inteleon in B, and Dynamax Kingler in C. It does not crack the useful part of the Dark or Dragon lists either.

Other community evaluations are kinder, ranking it around sixth among Water Max attackers and praising the tankiness. Both readings are true. It is a top ten Water option in a shallow pool that gets completely walled off by three Gigantamax forms. If you own any of those, Gyarados is a bench piece.

So who should evolve?

• Skip it if you already run Gigantamax Kingler, Inteleon, or Blastoise. Your 400 candy does nothing for your clear times.
• Do it if your Water Max bench is empty. A D tier attacker you own beats an S tier attacker you do not.
• Think hard if you have exactly 400 candy and no regular Gyarados, because Mega Gyarados enters Mega Raids on August 26 and needs a Gyarados to Mega Evolve. Same candy, very different payoff.

That last one catches people every year. Mega Gyarados is a legitimately strong Mega. Dynamax Gyarados is a D tier Max attacker. If you can only afford one Gyarados, the Mega is usually the better home for the candy.

Max Move upgrades and the trade trap

Every Dynamax Pokemon starts with its Max Attack at Level 1. Max Guard and Max Spirit start locked. Upgrading runs roughly like this, though the candy amounts shift by species cost group:

Now the part that matters most for anyone who uses this site:

Trading a Dynamax Pokemon resets its Max Moves to Level 1. The unlocks stay, but every particle and candy you poured into leveling those moves is gone. Evolving is safe and keeps everything, so Magikarp to Gyarados carries your investment fine. Trading does not.

The practical rule is simple. Trade first, invest second. Get the trade done before either side touches an upgrade. Line it up on the live trade feed and check the outcome with the trade calculator before you commit a special trade to it.

Farming Max Particles

You need 400 per battle and you can only hold 1000, so this is the real limiter today.

The 5 a.m. reset is the trick people miss. The window between midnight and 5 a.m. still counts as the previous day, so a late night loop and an early morning loop can both pay out before the sun is properly up.

Your Magikarp candy roadmap this week

This is the part that makes today worth caring about even if you decide Dynamax Gyarados is mediocre. The calendar is handing you a Magikarp candy pipeline.

One correction, because the internet keeps getting this wrong: the August 20 Spotlight Hour bonus is 2x Catch XP, not candy. If you were saving Pinaps for a candy multiplier, there is not one. You still get your normal catch candy and Pinaps still boost it, and mass spawns still beat any ordinary hour, so it is a great candy hour by volume rather than by bonus.

What it is genuinely spectacular for is XP. That hour sits inside the Water Festival 3x XP tier and stacks with the Spotlight 2x Catch XP. Pop a Lucky Egg at 6 p.m. on the 20th and throw at every Magikarp you see. It is comfortably the best XP hour left in August.

Debuts worth knowing about during the festival: Arrokuda, Barraskewda, and Cramorant all arrive. Arrokuda and Barraskewda come through Field Research, the GO Pass, and Rainy Lure Modules. Cramorant comes from Eggs, the GO Pass, and GO Battle League encounters. Shiny Ducklett and Shiny Dewpider odds are boosted too.

What to prioritize

1. Do a few Max Battles today, in person. The Rare Candy XL per completion is the best thing on offer and it is not species locked. Your particle bank caps at 1000 anyway, so spend it.
2. Do not evolve on impulse. Check your Water Max bench first. If Gigantamax Kingler, Inteleon, or Blastoise is sitting there, keep the candy.
3. Decide Mega versus Dynamax before August 26. One Gyarados, two very different jobs, and 400 candy either way.
4. Trade before you invest. Max Move levels do not survive a trade. Get the trade done first, upgrade after.
5. Lucky Egg at 6 p.m. on August 20. Spotlight XP on top of festival XP with Magikarp everywhere is the standout hour of the week.
6. Bank candy all week. Water Festival plus Spotlight Hour is the cheapest 400 candy will ever be for you this season.

Next two Max Mondays are Dynamax Hitmontop on August 24 and Dynamax Eevee on August 31, both 6 a.m. to 9 p.m. local. Eevee is the one to save particles for.
