People underestimate thesepeeps, especially Desann. Make your case for the others that's fine and dandy but Desann dueled Skywalker and TKED Luke ****ing Skywalker not to mention he brought down an entire damn bridge before he was empowered( permanently I might add) by the Valley of the Jedi.
Mara at this point had difficulty with a Vong who imo isn't all that impressive and only did so well because Mara was in an EXTREMELY disadvantageous state due to both her environment and Yomins weapons.
I'll admit that she likely blitzes through the first three. But here's what the rest got on here.
Zuma and Fy-Tor's speed will give Mara pause and since Fy-Tor's battlemind works well with others their synchronization will give them an advantage over a bloody, SICK Mara Jade.
Soara's a bloody legend and lightsaber master, she's surpassed both Kenobi(a master of the blade at 13 and counted among the best jedi nearing TPM) and Siri Tachi(the best padawan fighter several years prior to TPM and a jedi with incredible speed) in speed and skill. She's likely to give Mara pause as well.
Tavion, Tavion has TKed the crap out of Kyle(Mara's equal iirc) and her lightning brought a tired Jaden and refreshed Kyle(who literally waltzed in after Jaden killed everything ) to their knees. Not to mention Tavion can keep Mara at a distance with Lightning and The scepter. Again, giving a SICK Mara pause.
Xanatos, freaking Xanatos. A powerful dark sider as stated by Yoda, lightsaber prodigy, an equal to Jinn in force powers, stalemated his master on Telos to the point of exhaustion PRIOR to his prime, nearly killed Qui-Gon on bandomeer and it took two master lightsaber duelists to take him down with back up! His strength and speed are going to be a challenge for Mara.
Damn guys, don't any of you know what Mara was going through in Vector Prime? Ask jeez.
Edit: THANK YOU Q, Finally someone with a well thought out argument.
