Im not sure if it's already suggested, but i suggest to have borrowing and giving energy system. Like you stand near your friend and you ask him/her to borrow some of energy.Friend will give you some of his/her energy the same way like shoting generic beams.
It would be a good idea when you're the best player in server and ask for people to borrow energy, they will all give you energy so you can defeat the ultimate bot. TEAM WORK!
If you still don't understand what i mean, take a look at episode where Krillin and Gohan in Namek gives Piccolo theyr energy, or in Brollys movie when all the fighters give Goku some of theyr energy.
