Seannamus, the Aquatic Android is a custom champion for League of Legends, made by MrSuperSpy.


Glad and happy to see that you're taking some of your time out of your life to read one of my champion concepts, it really makes my day when someone cares for what I have to show and create. If you could provide feedback and express your opinion about this champion concept, you would make me a whole lot happier, but none of that now, because you're here because you saw the title of this post and thought either the name was interesting or you just follow my posts (definitely the former), so let's go on with the concept - meet Seannamus, the Aquatic Android.


Aquatic Design
RANGE: 450 (Cone)

Aquacy: Seannamus gains 0.75% cooldown reduction for every 10 bonus AD.

Robotic Charge: After every 4th spellcast, Seannamus' next auto-attack deals 30% AD bonus physical damage and explodes, dealing 60 / 80 / 100% AD physical damage to everyone behind the target (relative to Seannamus' position) in a 60° cone. The explosion can also damage structures, dealing 150% damage to them only.

Ability Details
Aquatic Design is a self-buff on-hit effect.
  • Applies spell effects as an area of effect ability.
  • As with most other on-hit effects, the triggering attack will apply other on-hit effects, life-steal and can critically strike as normal.
    • Critical strike chance modifiers to not interact with the explosion's damage nor the on-attack bonus damage.
    • The explosion does not trigger off of structures.
    • The on-attack bonus damage cannot damage structures.
    • The explosion will still trigger even if the attack was Counter Strike dodged, Riposte parried, Aegis Protection blocked, or if the attack Blind icon misses, but the on-attack bonus damage will not be applied.
  • Banshee's Veil item.png Spell shields will block the explosion.
  • This ability is considered to be a projectile for Unbreakable Unbreakable and Wind Wall Wind Wall.

AD-5 Aqua Rocket
RANGE: 900-1350
COST: 50 mana

First Cast: Seannamus starts charging a rocket, gradually increasing its range and damage by up to 50% over 2 seconds, but moving 20% slower (max. charge time: 4.5 seconds).

Second Cast: Seannamus fires the rocket, dealing physical damage to the first enemy hit. If the rocket was charged for over 3 seconds, it deals splash damage in a 150 radius circle, either when it hits a target or at the end of its travel. It can also be detonated mid-air.

  • Damage: 80 / 120 / 160 / 200 / 240 (+80% bonus AD)
  • Max. Damage: 120 / 180 / 240 / 300 / 360 (+120% bonus AD)

If Seannamus doesn't fire the rocket, he refunds 25 mana.

  • The first cast of Water Purge has no cast time and does not interrupt Seannamus' previous orders.


Seannamus is a human being robotized by Piltover's government in order to defend against invasions and attacks from the near ocean. He is cleverly designed to withstand any kind of underwater creatures and pressure in order to be of efficient use. His robotic armor is controlled by a top-tier processing unit stationed in his head, designed to emulate and imitate human behavior in order to blend in with the people in Piltover Underwater Sanctuary and be completely stealthed in the process as well. If anyone dares to threaten the peace, Seannamus initiates his robotic form, switching his hands to rocket launchers - mini rockets on the left and chargeable rockets on the right, turns on the Aquatic turbo-boosters on his feet allowing him easy treading in the ocean and transforms his chest into an arsenal of bombs and projectiles - the Aquatic Disruption Wave, Depth Separator along with the water shrapnel shells. If things are looking grim, Seannamus is equipped with a Purge system, allowing him to rapidly fire his abilities and then bombard enemies with their combined stored force. His armor's aesthetics consist of ultramarine blue with white accents and blue shades, along with pumps of electrolytes dissociated in water that power his 6000W battery.


Seannamus is a long-ranged marksman that utilizes his top-tier android technology to damage his enemies with rockets, bombs and shrapnel. He applies tons of pressure at a long range and has tons of damage as well, and when the enemy makes even a small mistake, Seannamus blows them up with his cooldown-less abilities and then buries them into the ground with his ultimate's heavy damage. His crowd control is also a force to be reckoned with - a nearly permanent slow and a heavy knock-up are just part of this robot's menacingly dangerous kit.

Early game is Seannamus' kingdom. He has incredible damage and very strong poke at a relatively low cooldown. His passive zones the enemy away from the creep wave, reducing their farm and gold per minute all while Seannamus happily pokes them with his signature AD-5 Aqua and Mini Rocket. With a good support such as Leona, Braum or Thresh, they can lock and burst down the enemy marksman thanks to the combined loads of CC, gaining a significant advantage during the early levels.
