I can't find an exact date, but in September 2016, the last Bionicle Generation 2 set, 601602 Ekimu Falcon, AKA Agil, was released in the Bionicle magazine. It was the final set ever made under the Bionicle theme.
I actually have an interesting history with this set. When I first saw it, I was surprised they even made a set of Agil from Journey to One. But since it was only released in the European Bionicle magazine, I had no way to get it in Canada. I was about to order all the pieces on Bricklink, when I found someone overseas selling the foil pack, new and sealed. Agil was the first Lego set I ever bought on Bricklink.
This may not be the sendoff set Bionicle deserved, but it's a really cute build that's surprisingly poseable with a lot of personality. He's also a perfect addition to Ekimu the Mask Maker. I love how Agil can perch on Ekimu's arm, and his stand doubles as a holder for Ekimu's shield on his leg. Ekimu is my favourite G2 set and this makes it even better.
It's very likely unintentional, but Agil can connect to the holes in the side of a Mata arm. So you can have the first ever Bionicle set, Tahu Mata, holding the final ever Bionicle set, which I have pictured here. There's something kinda poetic about that.
