The Battlefield Crossover RP (signups and discussion here) is yet another crossover roleplay created by Fusionman.
Battlefield Crossover RP contains examples of:
- Alternate Timeline: There are two Jack Russells taken from branching timelines, where they're on opposite sides of the war.
- Hammerspace: Jack can instantly swap weapons, armors, and accessories without having to actually take it off manually.
- Made of Iron: Jack has enough strength to weather through laser blasts, rock spikes, flying blades, orc fists... having magical armor helps too.
