I know that they are just used for gold and don't have thoughts or anything like that but I think we need a champion that the "master of minions"
It could be a minion that absorbed the power of an exploding nexus at the end of a match and gain power and sentient thought. He strikes a deal with the summoners of the league that he will become a champ if they create a village for the leftover minions to live in after matches.
Passive: grants bonuses to nearby allies minions.
regular: 10% attack speed
Tank: Slow enemy champs attack per attack.
Super: burn effect per attack. (2% of current health per attack)
Q: self-destruct. target ally minion will explode dealing magic damage equal to 25/40/65/80% of minion health to nearby enemies. Tank and Super minion will apply passive effect.
W: Rally. Heal and increase movement speed of all nearby allies and minions.
E: Target lock. All nearby minions focuses on chosen target.
R: Reinforcement. Next wave will spawn super minions. Lanes that are already spawning super minions will spawn an extra super minion.
Now it apparent what this champ weakness is: No minions or if in jungle, this champion is an easy target.
Now this is just a rough idea and the passive and R is what I really like the most, but I think a champ for the minions would be a fun thing for Riot to make. --- LIFE IS A BEAUTY HOWL! My favorite League of Legend Champion: http://i.imgur.com/xx0hSNV.png
