He was schooling bigfoot until he got caught.
Also, Reem won the K1 title in Tokyo which shows that he's a great striker
Indeed, Reem KOing Badr Hari in K1 was
HUGE at the time, many MMA fans started to really take AO seriously after that kickboxing bout.
Since the context around this upset might be difficult to understand for newer fans who weren't here at the time, and who could be confused as to why a non-MMA bout boosted Reem's stock so much, I figured I would explain in details:
Before the fight, Alistair was like 1-2 in old kickboxing bouts dating from 99/2001, hadn't fought in K1 for 4 years, was criticized for his "glass jaw" and even if he was getting some traction in MMA with his infamous horse-powered bulk-up, he was only at the start of his impressive run that ended when Bigfoot KO'd him in the UFC many years later...
On the other hand, Badr Hari then had been the K1 HW champion for a while, was considered one of the very best that K1 had to offer (Remy Bonjaski also had an argument for being the best HW kickboxer at the time) before the Reem fight, in which he (Hari) was a huge favorite.
Note: Badr was stripped of his champion title for his actions during the Bonjaski fight, (right before the Reem one), in which Hari socer kicked Remy after knocking him down, for seemingly no reason at all...
So Badr wasn't the official champion anymore, but he hadn't really "lost" the belt fair and square, which is why he was still considered the top dog in K1 despite being stripped of his belt.
A big factor to this fight's exposure was that they competed on a huge
Dynamite!!! card that had both MMA and Kickboxing bouts on it, so even the MMA enthusiast who usually weren't really into watching entire K1 events, were interested in this one.
Let's not forget that, at the time, the
"K1 level strikers" still had a big mystique on Sherdog, so for the fans, the outcome of this fight was pretty obvious... the K1 rebel golden boy Badr Hari would make short work of Overeem.
Plus, another important factor was that Alistair & Badr were supposed to fight twice; first with kickboxing rules, and at the next event with MMA rules.
So the consensus was that Hari would easily win the stand-up bout (Badr did a lot of trash talk, saying stuff like AO disrespected him by entertaining the idea that he could make the fight competitive), and that Overeem would have to submit him in the MMA rematch to have a chance at making it even.

Crazy upset, the MMA world goes nuts, and the
"K1 level striker" myth takes a huge blow (which was perhaps the last straw), and Hari later announces that, despite their previous agreement, he won't rematch Overeem under MMA rules and would stick to kickboxing for now, making Reem look even better in the process.
PS: I know that all of you who followed the sport back in 2008 already know all that, but as I said at the beginning, it's not an upset that is easy to comprehend if you weren't following the sport back then.
There are accomplishment in MMA that, even if you didn't witness it live, you can still get why they were such a big deal at the time if you educate yourself on the sport's history
Shogun's 2005 PRIDE GP victory for example, or Anderson Silva's UFC MW run, Sakuraba's victories of the Gracie family, Jon Jones' title run when he was running through lots of elite fighters like it was nothing, or even the insane hype behind fighters like Machida & Sokoudjou entered the UFC.
Then there are the ones that are more delicate to really get in hindsight, like Mark Kerr's run (nowadays lots of newer fans can just look at his record on go "meh, he just beat a bunch of nobodies from the look of it, what's the big deal?"), or why Ubereem got so much traction between his PRIDE days and his UFC debut.
I'd argue that Badr Hari played a big role in building Reem's aura of invincibility, and putting the final nail in the
"K1 level striker" , turning it into a meme...
