Steve Harrington
Steve at first seems like selfish jock that doesn’t care for others but behind the assumptions Steve is actually a kind, caring friend that will do anything to save his allies
“Turns out I’m a pretty damn good babysitter.”
Stars: 
Role: Tank
Position: Front-line
Entrance: Steve runs in, catching his breath than getting in position.
Victory: Steve puts his bat to the ground and smiles.
Defeat: Steve drops his bat and falls over.
Basic attack: Steve swings his bat at enemies knocking them back.
Skill-set:
White: “Second Wind”
Passive: You don’t go down easily. When Steve reaches 20% max HP Steve gains berserk for 5 seconds and heals to full health over the 5 seconds, when fully healed Steve takes 15% more damage after this passive is activated.
Active: To survive you have to put up your best defenses. When activated Steve gains 3 random buffs and 20% increased attack speed.
The attack speed increases can stack up to 200% increased attack speed.
Green: “Babysitter”
You make sure to protect those you care about, when a ally is defeated all other allies still in battle gain a moderate amount of armor and “Endurance”, “Endurance” protects allies from a enemy attack that does damage equal to 15% Max HP of any ally.
“Endurance” also blocks any negative effects while active on an ally.
“Endurance” expires after 10 seconds.
Endurance may fail to apply on allies that are of a higher level
Blue: “Camaraderie”
Trust is the strongest bond, any ally that heals or shields Steve gains endurance for 7 seconds and a moderate healing over time effect, any positive effects applied to Steve are shared with the last ally that healed Steve.
Purple: “Friendship matters”
Steve has a tremendous amount of basic damage for the first 10 seconds of battle, when Steve deals damage to an enemy with this buff active one random ally gains a shield for 4 seconds, shield times can stack on allies.
Red: “Scoops Ahoy!”
All allies have tremendously increased Max HP and considerably increased basic damage.
70% chance that a random ally gains berserk for 5 seconds when reaching 10% max HP
