halo has slip space (faster than light speed) the hunters in halo are actually a hive of worms that can take any form, I'd say that's about shape shifty enough (plus being a shape shifter will only help the flood) light sabers can't deflect a glassing bombardment and also the covenant have energy swords which do pretty much the same thing. Jar Jar, I just can't combat that XD yoda is pretty bad ass but I still don't think he stands a chance against the flood or halo rings. sith is the same argument as yoda clones would be wiped clean by Spartans alone the drones can fly (again flying would only help the flood) as I said before halo can glass a Death Star. also something I forgot to mention are the sentinels, these things can for into basically anything (they're what made up onyx) and they have more powerful weapons than the covenant.
