Iron man kinda inspired this champion concept. This champion is intended for top.

Evolving Armor (Passive)- Reinforced hextech armor will increase Reox's armor and magic resist over a time. After getting hit, it decays by a quarter. Gains 5/10/15 armor and magic resist for every 2 seconds not hit. Max is 25/50/75.

Arm Cannons (Q) - Your next auto attack will gain range and will apply a 3 second DoT on the target. As long as you don't switch targets, your attacks will keep the effect. (Max 3 auto attacks) Range = (125 + 400) DoT = 15/30/45/60/75 Physical damage (+0.2 bonus AD) (DoT's do stack) (40/60/80/100/120 mana) (10/9/8/7/6 second cooldown)

Thrusters (W) - Reox gains a burst of movement speed for 0.5 seconds and will ignore unit collision. This ability only has a one second cooldown, but if you use it within 3 seconds of first activation, the mana cost is doubled. (25/35/45/55/65% movement speed boost) (15/30/45/60/75 Mana)

Gamma Ray Burst (E) - (Active) Reox lets out a burst of energy around him, stunning enemies around him and dealing damage. In return, Reox's systems are shut down (silenced) and he cannot use abilitiies. 80/120/160/200/240 magic damage (0.2 AD, 0.5 AP) 1/1.2/1.4/1.6/1.8 second stun. 1 second of system shutdown. 16/14/12/10/8 second cooldown.

Gamma ray burst (E) - (Passive) When Gamma Ray burst is on cooldown, Reox's auto attacks deal more damage, and slow the target. (20/30/40/50/60 more magic damage on hit) (10/15/20/25/30% slow)

Final Form (R) - Reox leaps into the air (and is invulnerable) and jumps down to target location in a new suit (that has bonus armor and magic resist and bonus effects on abilities) knocking up enemies dealing damage. (150/250/350 damage, (1.0 bonus AD) (20/40/60 bonus armor and magic resist)

Final Form ability buffs:

Passive - You need to be hit 3 times for the passive to decay. 

Q: Gain 125 more range, and switching targets won't end the ability. (Still 3 auto attacks max)

W: During your 0.5 steroid, you'll gain 80% CC reduction, and 65% damage reduction.

E: (Active) The radius of the energy burst is increased, and your systems won't shutdown after activation.

E: (Passive) Auto attacks will also gain 25% attackspeed, and 20% increased crit chance.
