Tony awoke to a series of alarms and warnings
"Sir Power levels have dropped below 5%, flight power will only be sustainable for minuets if not seconds" warned J.A.R.V.I.S.
"Wha, wha, what happened? Where are we?" asked Tony
"Sir we received severe damage after your last bought with A.I.M. After you blacked out I diverted all remaining power to your chest piece and flight capability. Oh and we are currently 0.5 miles outside of Gotham City"
"How far can we make it on current power levels?" ask Tony
"Sir we will lose power before we clear Gotham"
"We're going to need help"
"Mr Wayne sir?"
"Yes"
Deep under Wayne manor Bruce Wayne sat in front of the Batcomputer studying recent crimes with a new form of energy weapons.
Alfred Pennyworth entered carrying a phone "Call from Mr Stark sir"
Bruce picked up the phone "Hi Tony how's New York?"
"Oh you now busy, fast under constant attack, oh I rebuilt Stark tower. Anyway I decide to ring to say I thought I'd drop in." quipped Tony
"Now's not a great time" replied Bruce.
"Yeah this was more of a heads up call"
With that Tony crashed through the waterfall hiding the cave and skidded to a halt half way across the steel grating of the Batcave.
Bruce ran over to him and flipped up the faceplate of his helmet.
"Tony are you ok?" asked Bruce.
"Your cave runs on its own power supply yes?"
"Yes why?"
"I need a recharge" Stated Tony with a smile.
Moments later Tony was standing with Bruce in front of the Batcomputer.
"When I was fighting A.I.M there weapons were charged with a unknown energy signature that threw my systems offline" explained Tony.
"Strange I've had similar problem I recognise the energy signature but not the schematics" said Bruce.
"Maybe we can help each other, J.A.R.V.I.S outline the foreign energy signature"
"Batcomputer show schematics of new energy weapons."
After a while Bruce put the pieces together.
"No, it can't be" exclaimed Bruce
"What?" asked Tony.
"Lex Corp is supplying A.I.M with weaponries kryptonite for their weapons."
