10 Edge System As Always-
marvel.wikia.com/d/p/3100000000000182515
Miles Edges In:
-Intelligence (Slight)
Reyes Edges In:
-Skill (Slight, the scarab gives him battle strategy and techniques to use in a fight).
-Durability (Scarab creates really tough sheilding thats protected him very well in battle against strong opponents).
-Invulnerability ^(same reason above, and armor that makes him bullet proof).
-Equipment/Weaponry
Reyes has many weapons to create and draw from (blades, blasters, flight equipment, and much more).
-Versatility
Reyes has alot more in his arsenal, including flight, making him the more versatile opponent.
-Range (Slight)
Due to flight and more powerful ranged weaponry.
Miles has his Webbing and Venom Blast (which has the potential to put Reyes down after a few hits), but Blue Beetles blasters and more are lethal to Miles, than Miles Webbing is to Reyes.
This is a really good battle. Strength, Speed, and Experience are very debatable imo.
-Strength. Both Miles & Reyes are capable of tossing cars, lifting cars, and have staggered powerful foes with their punches. They are equal.
-Speed. Reyes has flight yet Miles has Spidey sense, he'd be able to doge MANY of Reyes attacks. However it still would be difficult for Miles to land a hit if Reyes plays the distance gaming (flying around and attacking from a far). It would be difficult BUT NOT IMPOSSIBLE.. Reyes, would eventually have to come in close to defeat Miles because, again, his Spidey Sense would allow him to evade many og Reyes attacks. So in my opinion, neither has a definitve advantage of speed over the other.
-Experience. Both are Teen heroes, trained by more experienced comrades, been on super teams handling many different types of foes and challenges. Yes Reyes has the scarab, but it has not given him an extra advantage of experience (as far as I know), it just helps him in battle.
Blue Beetle out edges- My vote goes towards Reyes after a very good fight. His Equipment/Weaponry and Versatility makes him a greater threat. Miles' Venom Blast is too inconsistent (for me at least), one moment hes taking down Black Heart, next lower level villains are able to resist on some level. I dont even think the Venom Blast would be that effective against Reyes, the scarab possess adaptive abilities that could allow him to become resistant after ome hit...or even of Reyes was to be KOed by the Venom Blast, the scarab would take over and would still be able to fight. Also Miles Camouflage would be ineffective, the scarab allows Reyes to see invisible thimgs. Overall Reyes is more versatile with superior equipment and weaponry
