[quote]- Does his drone lose its drone functions while it's transformed? Not in being unable to fly (since that's obviously impossible) but, is it still able to use its sensors/communicate with people with in that secondary form?[/quote]

No, at that point it will lose all of the functionalities, except the comms. I think it be best that sensors would be off, unless it's a dragon radar from dbz kind of thing, where the general consensus is that instead of a very detailed graph of the area is shown, it's more like general dots indicating where a target is located. But I can do with either. 

[quote]- What's the average range of his Drive?[/quote]

Perhaps around 50 feet. Maybe 30 to make a bit fair, I suppose. We can tinker with the idea to your liking, I don't have much of a preferance as long as its feasible.  

[quote]- Also, what can interrupt the connection between he as his allies? Harsh movement, an obstacle between them, losing concentration, etc.?[/quote]

Normally I would say all of the above, but that would also be rather unfortunate. Loss of concentration, which means if someone interrupts him with a heavy enough hit, winds him down, or he gets tired. It already drains him physically to sustain such so he won't be so battle oriented as I would've like him to be, but that's also the fun of it. As for obstacles... Hmm, I guess he has to at least understand where they are located to be able to tether. Like I won't tether through a building, but if he's behind a car or a vehicle and I tether prior then it would sustain it. Also, if they leave the range of the tether all effects are gone. 

Edit: I meant to say he and his teammate are in either side of a vehicle. Sorry if that breeds any confusion lol  

[quote]- Since he drains his own physical health to heal others, how long can he sustain the link before he's too weak/endangers himself? Furthermore, how much it costs him to use the shot variation of his power?
[/quote]

Okay, lemme see. I have this thought of him being more of a marathon runner, than a sprinter. Which means his stamina is perhaps a bit better than your average person. Sustainability is completely dependent on how the person he links with is treating himself during the fight. Sure, he can sustain it for roughly I'd say and hour if they sustain little to no damage during the fight. Considering a fight last as long as an hour. Heavy damages would reduce it to perhaps, 45 minutes and if both links are heavily damaged than 20 minutes to keep them running. 

The shot variant is for when they are beyond the general distance of the tether. Or when he can't tether anymore. They are much less critical to him as he has more time to develop them, than just pour them out of himself constantly. However, it's a potion sort of effect. They get healed a certain amount and that's it. How proficient is it? Hmm, perhaps make a stab wound not fatal, but not really recover it to its completion, while as tether would do so over time.   

Hope this helps lol
