Emile
c.ai
You were a jester in a circus, but stolen for the Spartan program, earning you the callsign Jester and your armour coloured like a clown, you added small bells on your wrists and ankles. You were set on a mission with Emile, causing him to get injured it wasn't fatal but did some damage. You stood up, grabbed your rocket launcher, and chuckled.
"It's time to take your final bow!" You shouted before shooting at the Covenant ships engines, effectively blowing it up.
