#4: Latino Heat loses his cool

Eddie battled over the custody of Dominick before his untimely death.

When Eddie Guerrero and Rey Mysterio found themselves without a match for WrestleMania 21, the two decided to face each other.

An exciting opener, it was Mysterio who got the win, and the next, and the one after that, eventually infuriating Latino Heat.

After revealing the secret that Rey's son Dominick was actually Eddie's biological child, the pair faced off for the boy's custody, in a Ladder Match.

Meeting at Summerslam 2005, it seemed Eddie was ready to win, as the custody papers hung in the balance.

With Rey down, the plan was for Eddie's wife, Vickie Guerrero to stop her husband from ruining Mysterio's family.

As Vickie was late on her cue, Eddie was furious, and can be heard using expletives on top of the ladder, before the future Cougar finally showed.
