I'd like to amend that to: Has-Been -> Boxer -> Champ
and to add: Benchwarmer -> Football Player -> Star Player
I infected both the benchwarmer and the has-been, mostly out of curiosity, and they are definitely weaker (and slower) than the football player and boxer respectively. They are both slow in speed and medium in power. They earn low to average tips. The has-been is slightly faster than the benchwarmer. They both cost one toxin and both first appeared in my game at the beginning of level 15. If you can afford to burn one toxin on one of these, I'd say do so. To me, it's worth it for comedic value alone. I fired my CEO for the has-been, and tho my tips have definitely suffered consequently, at least the has-been can fight somewhat (unlike the CEO) and his energy lasts longer the CEO. No to mention, it is priceless watching the has-been underperform when both the champ and the has-been are serving. Lmfao, it's worth it for that alone. I named mine the Cardboard Boxer… The has-been's speed is very close to the fire chief's. Tho the has-been daydreams more often than the fire chief, at least he doesn't do so as much as Stoogey. Stoogey's tips and speed make up for his spaciness and fairly weak fighting skills (at higher levels) however.
