What is this missing number?

Shatter shrugged at the talking down not working, it was what she expected. A computer thinking it was doing its job when it was doing nothing of the sort, she was reminded of an old movie series but pushed it to the side when the curious dolls from before. Had formed into something that would turn the manliest guy into a blubbering child, Siren seemed herself frozen as well at the site of the thing which decided to come right for them.

Luckily she'd finally moved, Siren had rolled to the side prepared to fight however Shatter's instinct was different and she attempted to dodge up. Much to her dismay as the roof tried to reach out and grab her, in the few seconds she had before the thing grabbed her Shatter did two things. One was to send a burst of energy towards Siren that landed on her shoulder and formed into a Rilou, the second one was to form a barrier around herself before she was inevitably sucked into the ceiling.

The Rilou on Siren's shoulder nodded to Shatter's request about attacking from the sides and jumped the crazy beast and waited for Siren to make her move before it went for the attack. Meanwhile Shatter was being dragged through digital brick and mortar being attacked on all side, as Archon tried to break through her barrier in an attempt to bring Shatter to her side.

"Shatter!" Siren called out but it was too little, too late as she could only watch her companion be hauled off into the ceiling, making it clear that the A.I. could make the building itself attack them. At seeing the creature on her shoulder though, she got the message, "Ok, little guy...let's take this thing down!" She zipped around like a bird before aiming both maces forward as she flew towards the thing's face, "Now, Riolu!"
