Shark Type Champion Suggestion

So, we obviously already have that slippery buttmunch Fizz, but we should get a shark champion, perhaps in lore he haunts the waters of Bilgewater, looking to kill people. It would be a type of Vastaya Shark/human creature with a right arm that is basically a super sharp shark fin. He could be a bruiser type jungler. example kit He would use ferocity as his resource bar

• Passive - Land Legs - Increased movement speed and resistances/damage/lifesteal in the river. At 4 stacks of Ferocity he would recieve bonus 25% bonus MS and this could stack up to 3 times (stays active for 10s)
• Q - Death Swoop - swooping attack (with his sharp fin thing) that gives ferocity (kind of like camille w ), does the same damage in all regions, but if it hits on the outside the target is slowed and gives a bonus stack of ferocity (9/8/7/6/5 s Cooldown)
• W - Savagery - triggers on attacking, next 3 attacks deal bonus true damage/lifesteal, final attack dealing a small amount of AoE damage and generating ferocity ( 18/16/14/12/10 s Cooldown)
• E - Thirst for Blood - he smells for blood, allowing him to see all enemy champions below 60% health, he does not gain any increased movement speed or anything, but gains vision on the target and the next attack on the target will stun and heal him for a small amount, generating ferocity (21/18/15/12/9 s Cooldown, 1/1.25/1.5/1.75/2 s Stun)
• R - Ambush the Weak - If the target enemy champion is stunned/rooted you leap to them, dealing 200/300/450 base AD on impact, if you use this from melee range it will instead deal true damage to the target and instantly refresh Savagery

Could be allies or enemies with fizz, tahm kench, or nautilus.
