Arthur Collins has appeared at Wood Green Crown Court for the trial in which he denies five counts of grievous bodily harm with intent after throwing acid in a nightclub.
Collins, 25, was apparently wearing a t-shirt with the word "killer" written across the chest when he threw the acid three times across the crowd, leaving 17 people seriously injured by the attack.

The attack, which took place at the Love Juice event at Mangle nightclub in Hackney, London over the Easter weekend, left two victims partially blinded and a further 15 with disfigurements.
Apparently, Collins, whose ex-girlfriend Ferne McCann is pregnant with his baby and preparing to give birth, was involved in a brief altercation with a group of men in the VIP area, before coming "out of nowhere" and throwing acid into a man's face at around 1am.
As people pulled him away, he threw the acid twice more which hit unsuspecting people, prosecutors told the court.
Whilst Collins has admitted throwing the liquid, he claims that he did not know it was acid.
His co-defendant Andre Phoenix, 21, also denies the charges.
Prosecutor Luke Ponte told the court: "It is the Sunday night of the Easter Weekend and people are out and about like it is a Saturday night.
"The dance floor is crowded, it's packed, people are enjoying themselves, just like any other club in the country. And again, just like anywhere else, a bit of trouble flares up. Nothing much at first, the beginnings of an argument.
"It doesn't amount to much, some pushing some shoving, some young men, some raised voices but it quickly escalates. It is not clear how this trouble started but it is very clear how it ended, suddenly and decisively, and not at all in keeping with what had gone before.
"One of the young men, perhaps perceiving the threat of a knife, threw acid into the face of another young man. As that man went down in pain, the aggressor threw acid at them a second time towards another young man, and then a third time.
"You will see, in due course, the consequences of those actions, they were just as you would expect on a crowded dance floor, on a popular night."
He added that it was "no dispute" that Collins threw the acid: "That he does not dispute it is perhaps unsurprising, as the confrontation, the first throwing, the second throwing and the third throwing are all captured quickly but distinctly on the club's CCTV."
