The Hero we need... or at least the one I want

A tank that can change form. And I don’t mean Bastion.
His secondary weapon allows him to swap between 5 forms (can only swap while at full health) that are full armor - mostly armor - balanced - mostly barrier - full barrier. He would have 100HP + 400 (400 armor/0 barrier - 300 armor/100 barrier - 200/200 - etc)
He would also have abilities corresponding to A or B:
E: spikes that reflect parts of damage taken (the more armor focused the better)
L.Shift: makes him resistant to CC (A) or increases speed and jump height (B) - full A means long resistance but no increased speed, balanced A/B means both for a moderate time, etc
R.Click: alternate attack that jumps to 1-4 additional targets depending on how much B he has.
Ult: full A and B for a limited time

Who’s with me?^^
