@Zz'acc, [member="Darth Kentarch"], [member="Ember Rekali"]
They were in an underground facility that was beneath a hill of some sort, Siobhan and Ember had already made it down a couple levels. Ergo there would be no nearby building to burst through or vehicles to clamber over, though plenty of dead bodies on the levels above them. A Zillo beast was indeed powerful and with a hide that could even resist a lightsabre, however, it ought to find it very difficult to manoeuvre. Let alone simply fit in. After all, it was very unlikely that the Sith had constructed their base with the needs of a creature that was 6,7 m tall and 62 m long in mind.
Sith were not known for their belief in equal opportunities, but to be fair there were not many Zillo Beast Sith Spawn running around freely! Generally force roar was also a power that could not be forced.
Regardless, Zz'acc was somehow in the facility, but a gigantic beast like that moving was the exact opposite of subtle. He was also trying to utilise what amounted to a shockwave against Siobhan Kerrigan, apex telekinesis master, who had a habit of being concussively unkind to people. She only about three offensive force powers, but was highly specialised in them. Her most significant speciality was to throw...very heavy objects. As in grip walkers and toss them around as if they were ragdolls - or summon shockwaves of sufficient strength to punch through the hull of a Star Destroyer, grip a bridge tower and crush it with all her might.
She sensed the shift in the air currents and exerted her telekinetic will, with aphotic energy writhing within her as power burst from her hand. With her prowess any energy directed towards her by the great beast would not be dissipated, but overridden, an overwhelmning outburst of telekinetic power that would sweep towards the Zillo beast with great force. He was strongly armoured obviously, but the shockwave was such to punch a hole through a battleship. Her telekinetic might had faced Cthulhu before after all, or rather the skyscraper-sized Lotek'k. Moreover, given his very substantial size, dodging would not be much of an option. The force blast shot towards him with a force that should send crashing into, or rather through a wall, for it would be blown up in the explosion of power as she poured her energy into harnessing the Force like a battering ram.
Beads of sweat dripped down her forehead and temples, but she persisted. Siobhan was not subtle, she was not graceful and many of the more arcane mysteries of the Force escaped her, but she had a great deal of energy and plenty of power to dish it out and her grip had torn down many a ceiling, even brought down that of a mountain. The hall would shake like struck by quakes, as if an earthquake had broken out. Then, stretching out her bionic hand, the energies of the Force flowing through her, she wrapped her telekinetic willpower around the ceiling above him, heaving with her power upon it, the roof wobbling and shaking under the stress. Fingers curled into a twist, metal twisted and cracked, then the roof of the corridor above the beast would be torn down by the brunette juggernaut, seeking to bury it.
