Amazing Champion Concept Idea!!! Mechanus, The Machine Lord

A hulking metal behemoth armed with state-of-the-art Noxian/Zaun weaponry consisting of Gatling gun/Plasma blaster, Voidian Energy Boost, Gravitational Pulse, and a Massive array of missiles to be launched with a button push. To start, passive part 1 is he uses Heat as resource and using spells heat him up, with the cost ramping up with level and also giving him more heating space, part 2 is upon gaining a point in his r he gets to upgrade one of his abilities like Kha'Zix to have enhanced effects. Q is Generic gatling gun to start and has 525 attack range and with a point can cast it to swap to his plasma blaster where every three attacks set the foe on fire and deal bonus true damage when they're on fire, but each plasma bolt generates like 5 heat scaling with level. W is Voidian Energy Boost which sends out a helping drone for 1 minute which increases damage and ap of everyone within a small radius, if cast on a player it will follow them around, and increases health and movement speed for them and in a small radius around the player instead of the power boost. E is Gravitational Pulse Which either absorbs or sends out everything around you. R is sending out a huge swarm of missiles that assault an area for 3 seconds and fall faster the closer they are to you. Enhanced Abilities: Q is more potent and you have 20 more range on basic attacks, and heat is reduced for plasma blaster. W Enhances the radius of the buffs and gives both sets when on a player. E has a longer pull/ push range. R causes the missiles to home in on anything within a 375 radius of their landing point, they will keep tracking even after the target has left area for 5 seconds before they drop and explode on the spot. NOTE: When heat is full all powers will be locked and you will receive a 25% movement speed and Armor/MR boost while cooling down. I'm thinking that the model can evolve with every upgrade like Kha'Zix, like the weapons get bigger! (Sorry that there are no pics, I am bad at drawing champs, even ideas I made lol, Have fun and pls make Mechanus Happen!)
