Parasitic Champion

So i was thinking of a Melee Champion (Top Laner/Jungler/support) its First ability can shoot a parasite at an enemy unit dealing damage over time if the the parasite is still on the unit when the unit dies the parasite takes over its corpse attacking enemy units (cannot take over champions/large monsters corpses), prioritizes enemy champions when targeted by the controller and vice versa. Second ability is to empower its basic extending its range for the attack (Range is doubled if the target has a parasite on them) dealing an extra damage based off AD + dealing missing health percent damage. Its Third ability is to make a parasitic egg if stepped on it stuns dealing a small amount of damage over time to enemy units, if the egg is attacked the egg hatches a parasite comes out and jumps on a near unit (prioritizes champions if near) if an ally champion activates the egg the parasite latches on the ally champion and heals over time based off bonus health from user. Its Ultimate ability is a passive when the user dies it can launch a larger parasite from the corpse as a skill shot that latches on to an enemy champion dealing damage over time and if the enemy champion dies while this Ultimate parasite is still in effect you it will revive you at the enemy's corpse with 5% health. Its Passive gives it massive but fair amount of movement speed when moving toward a unit that has a parasite on them.
