Akos (in armor)

Self repair. The advanced technology of the armor makes it able to repair it self. At the start of his turn, Ákos's armor heals 6+1d8 if it has more than 0 Hp.

Sealed. The Armor completely seals the wearer from the outside world, so it protects the user from the conditions listed above, and from any poison damage. Further more the armor has great insulation, so heat can't enter the insides of the armor. This makes it invincible to heat metal and such.

Heavy Punch. Melee Weapon Attack: +8 to hit, reach 5 ft., 1 target. Hit: 14 (2d8 + 5) bludgeoning damage. 

Lightning bolt. RangedWeapon Attack: +6 to hit, range 45 ft., 3 target. Hit: 13 (2d6 + 6) lightning damage.

Double slap. Melee Weapon Attack: +5 to hit, reach 5 ft., 2 target. Hit: 7 (1d8+3) bludgeoning damage. (Can't be used if someone is grabbed by Ákos)

Electrolyze self. Charges the outside of the armor with electricity. Until the end of Ákos's next turn, anyone who attempts a melee attack, takes 2d4 lightning damage. (Can't be used in the same round as Lightning bolt)

Grab. Melee Weapon Attack: +8 to hit, reach 5 ft., 1 target. The target can use their reaction to make a DEX saving throw to try and avoid this effect (the DC is Ákos's attack roll +8). If this attack hits, the target is grappled and restrained. The target can attempt a saving throw at the end of their turn, in this case Ákos has to repeat the attack roll, spending his reaction.

Counter fire. If someone attempted to attack Ákos with a ranged attack and failed, Ákos can counter fire a small lightning bolt that deals 1d6 +3 lightning damage.
