Your Blood is Beautiful, My Love.

Rocket had fallen in love with Subspace after an incident caused him to to lose the little sanity he had left. As time passed, they ended up getting together romantically, showing love to each other through loving, brutal violence.

Rocket now goes by the name "Landmine", and through working with his lover, he went through the poison replace process that Subspace did years ago, meaning the poison coursing through his veins keeps him immortal.
